过去，我可以通过以下方式将 MOBO 模拟音频输出更改为 ZOTAC HDMI 音频输出：
pactl set-card-profile 0 output:hdmi-stereo
和
pacmd set-card-profile 0 output:analog-stereo
但那是在我拥有一个 GPU 时，它通过 SPDIF 将音频从 MOBO 传输到 GPU。现在我拥有一个 GPU，它可直接从 PCIe 插槽获取音频。
我需要使用什么命令？我知道它在 GUI 控件中运行良好。我只需要它通过命令行工作。切换显示的部分已经起作用了。
答案1
这取决于你的情况。我从 HDMI 切换到模拟，
pacmd set-card-profile 0 "output:hdmi-stereo-extra1+input:analog-stereo" # To HDMI
和
pacmd set-card-profile 0 "output:analog-stereo+input:analog-stereo" # To analog
你可能想要把这些放在alias。
